Step‑by‑Step Instructions for Spicy Southern Cheesy Chicken Spaghetti Casserole
Step 1: Preheat Oven
Begin by preheating your oven to 350°F (175°C). While it warms up, grease a large casserole dish with cooking spray or butter to ensure easy removal later. This step is crucial for achieving that delicious, bubbly crust on your Chicken Spaghetti Casserole.
Step 2: Cook Chicken
In a large skillet over medium heat, add a splash of oil and place boneless, skinless chicken breasts. Cook them for 6-7 minutes on each side until they are golden brown and fully cooked through, checking that the internal temperature reaches 165°F. Remove from the skillet and let them rest before shredding.
Step 3: Boil Pasta
In a big pot of salted boiling water, cook the spaghetti for about 8-10 minutes until al dente. Once cooked, drain the pasta in a colander and set it aside, allowing any excess moisture to evaporate. This will help keep your Chicken Spaghetti Casserole from becoming watery.
Step 4: Mix Ingredients
In a large mixing bowl, combine the shredded chicken, cooked spaghetti, cream of chicken soup, chopped bell peppers, paprika, cayenne pepper, garlic powder, and half of the sharp cheddar cheese. Mix everything thoroughly until well combined, letting the flavors meld beautifully to elevate your casserole.
Step 5: Assemble Casserole
Transfer the mixture into your prepared casserole dish, spreading it out evenly. Top it with the remaining sharp cheddar cheese, creating a melty blanket that will enhance the dish. This step ensures that every bite of your Spicy Southern Cheesy Chicken Spaghetti Casserole is filled with cheesy goodness.
Step 6: Bake Casserole
Place the assembled casserole into the preheated oven and bake for 25-30 minutes. You’ll know it’s ready when the cheese is bubbly and golden brown, and the edges start to slightly crisp. The wonderful aroma will fill your kitchen, tantalizing everyone’s taste buds.
Step 7: Garnish and Serve
After removing the casserole from the oven, let it sit for about 5 minutes to set. Then, sprinkle chopped green onions on top for a fresh crunch and a burst of color. Your delicious Chicken Spaghetti Casserole is now ready to be served and enjoyed with family or friends!
